Is the select list wrapped in a form? IS the form a GET or POST method?
If you change it to a GET then you can see the URL when the form is
submitted. There should be something like
http://localhost/serverlet/MyServlet?groupList=Michael&GroupList=John
But remember, they also have to be highlighted as well, just listing them won't
make them selected. Since you are building the list dynamically, with the
onSubmit event handler on the form you can add a loop which sets all the
elements of the select list's selected value to true ...
